Glaucia was a Naiad Nymph of the River Skamandors (Scamander) in the Troad (north-western Anatolia). She was loved by the hero Deimakhos (Deimachus), a companion of Herakles.
Glaukia, a daughter of the rivergod, Scamander. When Herakles went to war against Troy, Deimakhus, a Boeotian, one of the companions of Herakles, fell in love with Glaukia. But Deimakhus was slain in battle before Glaukia had given birth to the child she had by him. She fled for refuge to Herakles, who took her with him to Greece, and entrusted her to the care of Eleon, the father of Deimakhus. She there gave birth to a son, whom she called Skamander (named after her father), and who afterwards obtained a tract of land in Boeotia, traversed by two streams, one of which he called Skamander (in honor of his grandfather) and the other Glaukia (in honor of his mother). He was married to Akidusa, from whom the Boeotian well, Akidusa, derived its name, and had three daughters, who were worshipped under the name of "the three maidens."
